This "study" uses a flow model to model blood flow through the carotid artery. Their conclusion is that people, with partially blocked arteries, could have a stroke caused by elevated heart rate during exercise. There is zero evidence that this really happens, but this study could encourage people to not exercise, despite the evidence that exercise is healthy and increases lifespan.

This looks like another example of unhealthy lifestyles being encourages rather than healthy lifestyles.
